A special air quality statement was issued on Sunday morning by Environment and Climate Change Canada (ECCC) due to smoke.
"Wildfire smoke concentrations can fluctuate over short distances and vary considerably from hour to hour. Wildfire smoke can be harmful to everyone’s health even at low concentrations," ECCC reminded residents.
People with lung disease (such as asthma) or heart disease, older adults, children, pregnant people, and people who work outdoors are at higher risk of experiencing health effects caused by wildfire smoke.
Residents are also reminded to stop outdoor activities and contact their health care provider if or someone in their care experiences shortness of breath, wheezing (including asthma attacks), severe cough, dizziness or chest pains.
You should stay inside if you are feeling unwell and experiencing symptoms.
"Take a break from the smoke by temporarily relocating or finding a location in your community with clean, cool air such as a library, shopping mall or community centre."
The air quality statement is in effect for Airdrie, Cochrane, Olds, and Sundre.
